r markdown biblio-style 不起作用

我在改变论文中参考书目的引用风格时遇到了一些麻烦。根据r-降价指定围兜样式（我需要acm from latex）我只需要执行以下操作：

---
title: "title"
bibliography: biblioteka.bib
biblio-style: acm
output:
    pdf_document
---

但是，那biblio-style: acm似乎对引用风格没有影响。

当前引用:

随机森林已经应用于信用评分[@author1] ...

@Article{author1,
   Title                   = {some title},
   Author                  = {Einstein},
   Year                    = {1997}
}

期望的输出:

随机森林已经应用于信用评分[1] ...

References
[1] Einstein, some title, 1997

对我来说最有效的另一种可能性是添加引文风格语言 (CSL)文件 - 在您的情况下是 acm.csl - 并在 YAML 标头中引用它。打开文本编辑器并将以下 XML 代码复制到其中，将其保存到工作目录中并将其重命名为“acm.csl”。

</style>

之后，在您的 YAML 标头中引用此文件：

---
title: "title"
bibliography: biblioteka.bib
csl: acm.csl
output:
    pdf_document
---

要更改样式，只需在以下位置找到另一种引用样式即可CSL-网站并使用不同的 *.csl 进行相应操作。

为了完整起见，您需要在论文末尾添加参考书目：

# References
```{r refmgr references, results="asis", echo=FALSE}
# PrintBibliography(bib) 
```
